From 6c7be7d385f4911895877e0f0697c598f600136f Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Fri, 26 Jan 2007 19:07:51 -0800 Subject: [PATCH] [POWERPC] ps3: repository storage support Handle storage-related repository data: - Add missing implementations of ps3_repository_read_stor_*() repository accessors. - Dump storage properties in debug mode - Add PS3_DEV_TYPE_STOR_{DISK,ROM,FLASH} device types (which are identical to the corresponding SCSI device types) to enum ps3_dev_type Signed-off-by: Geert Uytterhoeven Signed-off-by: Geoff Levand Acked-by: Arnd Bergmann Signed-off-by: Paul Mackerras --- arch/powerpc/platforms/ps3/repository.c | 185 +++++++++++++++++++++++- include/asm-powerpc/ps3.h | 24 ++- 2 files changed, 200 insertions(+), 9 deletions(-) diff --git a/arch/powerpc/platforms/ps3/repository.c b/arch/powerpc/platforms/ps3/repository.c index 9ef31a5b7035..2416bfadec9e 100644 --- a/arch/powerpc/platforms/ps3/repository.c +++ b/arch/powerpc/platforms/ps3/repository.c @@ -368,7 +368,55 @@ int ps3_repository_dump_resource_info(unsigned int bus_index, return result;
